Guide gun question
« on: February 06, 2004, 02:24:57 PM »
I have always wanted a guide gun in .45-70 but I have a really dumb question. I you put .45 colt ammo in it, would it fire? Would it be safe?

The 45 colt bullet dia is .452 vrs .458 for the 45/70 so accuracy would stink. I doubt that there is enough in common between the two casses to function correctly in a lever action. Would it fire?  Maybe, but the outcome would not be to your liking.   KN

NO! Compare the two rounds they are so different in size that you would be asking for a ruptured case.

A simple rule of thumb: If it isn't marked on the barrel it doesn't go in the gun!

There are a few exceptions such as .38 Spec in a .357 Mag ditto for .44 Spec. in  a 44 Mag.

At least you were smart enough to ask FIRST that shows smarts. Sean

Along your line of question, a few years ago, I heard you could run 44 mag ammo in a Marlin 444.  You cannot!

WWG does a conversion that would allow a 457 Mag to chamber, and still allow 45-70 ammo - the reloader gurus advised that t 45-70 can be hand loaded to nearly the same power, and advised that in not necessary.

Some of the older 1994s will not run 44 specials, only 44 mags.

If you are wondering about being able to plink with a 45-70, there are over 25 different factory loads, and some almost a light recoiling as a 30-30.  Others heavy enough that you might want to wear a mouthpiece to protect your teeth.

I know the guide gun can fire the .410 shotshell also but that it must be handloaded into the chamber, it won't cycle through the action. Anybody got any idea if a .45-70 shotshell could be made up? How would you do it? Would it be a real pain in the...?

missouri dave,

If someone makes the plactic capsules for shot in .45 caliber, you might be able to gin up something, although I don't know if you could get it to feed.

Also, the shot weight would be pretty low since these capsules are designed for handguns.

Why do it?45-70 ammo is already cheap and if you reload it could be close to 45 Colt factory stuff.Especially if you use the Remington inexpensive bullet.

The Guide gun in 45-70 or .450 is impressive at the least meant for Big Game.Practice is practice,load them down and enjoy.

Just my opinion.Jayco aka Jay Billie Bob.

Even cheaper, lead bullets are easily obtainable for the .45-70.  Using the Springfield loading data you can come up with a light recoiling load that is dirt cheap to shoot.

Of course, if you really want to have some fun, fill the case up with 2F black powder and seat a lubed cast bullet on top of it.  :grin:

missouri dave -

Bad idea, as you have probably gathered by now.  The difference in case sizes just ahead of the rim is 0.255" - the .45 Colt case masures 0.4800" and the .45-70 measures 0.5055".  As has been pointed out, a ruptured case is highly likely.

For shooters wanting reduced power loads, there is an excellent solution for handloaders - download the .45-70 to .45 Colt velocities.  Using loads derived from data at www.gmdr.com, I developed two different loads using 300g and 350g hardcast over 13.5g HS-6 and a CCI 200 primer.  Both loads shoot about 1100fps and are deadly accurate, with minimal recoil.  Cost is about $2.50 per box of 20 to reload, and they are incredibly fun to shoot.  

Of course if you don't reload, the .45-70 is a great reason to get started!

:) Dave, What's stamped on the barrel is what you put in the chamber, If you value your eye's and fingers. Buy a 45/70 and a 45 colt and live happily ever after...
